Emudeck on the Steam Deck is absolutely insane. I wink winked Snes Rom collection and put them all on my steam deck and hot damn, Emudeck configured the games so that all of them have their own box art and are easily accessible from the Steam Decks UI. You can just hit play like you would any normal game and it just works.
